CO2 can be captured through both natural and man-made (technological) processes. Taking advantage of the Earth's natural carbon capturing abilities - by growing trees and algae, improving farming practices, enhanced weathering, and using Bio-Energy with Carbon Capture and Storage (BECCS) - allows us to use proven natural methods to capture large amounts of CO2 from the atmosphere. Some of the methods, such as enhanced weathering, can also improve soil quality and crop yields. 

Using technological methods to capture CO2 presents us with a way to capture emissions and use them to create products. Machines that pull CO2 out of the atmosphere and newly discovered ways to turn that CO2 into the building blocks of materials we use every day are opening up a new world where we can begin to bring down the amount of CO2 in the atmosphere in an economically viable and socially beneficial way. New start-ups and large corporations are constantly adding increasingly efficient and effective tools to the current CCUS arsenal.
